This document is an appendix to Authoring Tool Accessibility Guidelines 1.0, which has been
reviewed by W3C Members and other interested parties and has been
endorsed by the Director as a W3C
Recommendation. It is a stable document and may be used as
reference material or cited as a normative reference from another
document.

This checklist includes all checkpoints from the Authoring Tool Accessibility Guidelines 1.0,
organized by priority, as a checklist for authoring tool developers.

Checkpoint Priorities

Each checkpoint has a priority level. The priority level reflects the
impact of the checkpoint in meeting the goals of this specification. These
goals are:

That the authoring tool be accessible;

That the authoring tool produce accessible content by default;

That the authoring tool encourage the creation of accessible
content.

The priority levels are assigned as follows:

[Priority 1]

If the checkpoint is essential to meeting the goals.

[Priority 2]

If the checkpoint is important to meeting the goals.

[Priority 3]

If the checkpoint is beneficial to meeting the goals.

[Relative Priority]

Some checkpoints that refer to generating, authoring, or checking
Web content have multiple priorities. The priority depends on the
corresponding priority in the Web Content Accessibility
Guidelines
(WCAG) 1.0 [WCAG10].

It is priority 1 to satisfy the checkpoint for content features
that are a priority 1 requirement in WCAG 1.0.

It is priority 2 to satisfy the checkpoint for content features
that are a priority 2 requirement in WCAG 1.0.

It is priority 3 to satisfy the checkpoint for content features
that are a priority 3 requirement in WCAG 1.0.

For example:

Providing text equivalents for images
and audio is a priority 1 requirement in WCAG 1.0
since without it one or more groups will
find it impossible to access the information. Therefore, it is a
priority 1 requirement for the authoring tool to check for
(4.1) or ask the author for
(3.1) equivalent alternatives for these types
of content.

Grouping links in navigation bars is a priority 3 in WCAG 1.0. Therefore,
it is only priority 3 for the authoring tool to check for
(4.1) or ask the author for
(3.2) groups of links that are not grouped
in the markup as a navigation mechanism.

When a checkpoint in this document refers to the WCAG 1.0 [WCAG10], only
the WCAG 1.0
checkpoints that refer to content supported or automatically generated
by the authoring tool apply. Some of the applicable WCAG 1.0 checkpoints may
be satisfied automatically (without author participation) while others
require human judgment and support from the tool in the form of prompts
and documentation. Different tools may satisfy the same checkpoint
differently.

The priority level for each checkpoint has been chosen based on the
assumption that the author is a competent, but not necessarily expert, user of
the authoring tool, and that the author has little or no knowledge of
accessibility. For example, the author is not expected to have read all of
the documentation, but is expected to know how to turn to the documentation
for assistance.

Checkpoint 3.4 Do not automatically generate equivalent alternatives. Do not reuse previously authored alternatives without author confirmation, except when the function is known with certainty. [Priority 1](Techniques for 3.4)

Checkpoint 7.1 Use all applicable operating system and accessibility standards and conventions (Priority 1 for standards and conventions that are essential to accessibility; Priority 2 for those that are important to accessibility; Priority 3 for those that are beneficial to accessibility).
(Techniques for 7.1)

Checkpoint 4.5 Allow the author to transform presentation markup that is misused to convey structure into structural markup, and to transform presentation markup used for style into style sheets. [Priority 3](Techniques for 4.5)
